HP Lefthand SAN and VSS Snapshots for Backup
I was wondering if someone could give me a basic overview on how this is supposed to be structured as I'm struggling to get it to work. The help files are good on details, but give very little information on how to structure the volumes and data.
I have 6 HP Lefthand P4300G2 SANs connected to a cluster of 4 Windows 2012 servers running Hyper-V.
I am trying to set up a new backup using either Veeam or DPM. I have the Application Aware Snapshot Manager Installed on the Hyper-V Servers, and it is authenticating correctly to the SANs.
This is the point where I think I may have made a mistake with the setup - The SANs are hosting a single 40TB volume which is shared to the Server Cluster over iSCSI. This works fine, and all my Virtual Servers are held on this 40TB volume.
When I try and take a backup using either Veeam or DPM, I get an 'out of space# error in the event log, see below:
HP LeftHand VSS Provider: Failed to take snapshot during CommitSnapshots , 0x80001010 - Sending Multiple Operation Failed: Insufficient space to make the requested change.
Is the SAN trying to snapshot the entire 40TB volume and is this why it fails? Should I have created a separate volume for each virtual server. If so, that seems like a lot of work to manage, especially as the volumes are connected using MPIO.
There is 9TB of unallocated space on the SANs and the server I am trying to backup is only about 100GB. Do I need to allocate this space in some way maybe?
Does anyone have Veeam or DPM working using HP Lefthand SANs? How did you structure it?
